Principal Design Features
|
|
An alloy of nickel and chromium intended for high temperature use as electric resistance heating elements. This alloy increases in electrical resistance as it gets hotter. Typical is a 6% increase at 1600 F over the room temperature resistance
|
|
|
Applications
|
|
Used as heating elements in electric appliances and electric industrial furnaces and ovens.
|
|
|
Machinability
|
|
The alloy is readily machined by conventional means.
|
|
|
Forming
|
|
This alloy is usually furnished as wire or strip and it may be readily formed into various configurations, such as coiling for wire forms.
|
|
|
Welding
|
|
May be welded by all the standard techniques.
|
|
|
Heat Treatment
|
|
Anneal at 2050 F to 1950 F and air cool.
|
|
|
Forging
|
|
May be forged in the 2050 F range.
|
|
|
Hot Working
|
|
May be hot worked from 2000 F to 1400 F.
|
|
|
Cold Working
|
|
The alloy has good ductility and is readily cold worked. Cold working will cause work hardening.
|
|
|
Annealing
|
|
Anneal at 2050 F to 1950 F range.
|
|
|
Hardening
